EGG-TESTER.

SPECIFICATION forming part of Letters Patent No. 378,853, dated February28, 1888.

Application tiled September 3, 1887. Serial No. 248.717. (No model.)

To aZZ whom it may concern.-

Beit known that I, RUDOLPH Sfrucxwrson, of Cory, in the county of Clayand State of Indiana, have invented certain new and useful Improvementsin Egg-Testers; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had totheaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification, in which- Figure l is a frontview of my improved egg-tester with the movable reflector down. Fig. 2is an end View of thesame, showing the movable reflector down in dottedlines and raised in full lines. Fig. 3 is a transverse section throughthe tester.

This invention relates to improvements in egg-testers; and it consistsin the novel construction and arrangement of parts hereinafterdescribed, illustrated in the drawings, and particularly pointed out inthe claims hereto appende Referring to the accompanying drawings byletter, A designates a rectangular or other proper shaped box whichforms the body of the tester, and which is closed at back and ends andbottom, if desired, to exclude light. The front of box A has ahorizontal slot or sight-opening, a, at its upper edge, as shown, andhereinafter referred to.

The top B of Vbox A has its ends projecting somewhat beyond the ends ofthe box, as shown, and this top B is provided near its edge adjoiningslot a with one or more circular openings, C, in which are placed theeggs to be tested.

c designates a wire or cord secured between the ends of box A,underneath and in line with openings C C, by which the eggs areprevented from falling through said openings, should the eggs placedtherein happen to be smaller than the openings C in diameter. The edgesof openings C and the wire c, if desired, are preferably padded insuitable manner to prevent accidental breakage of the eggs whendeposited in said openings.

D designates a mirror mounted inside box A, underneath and in rear ofopenings C and wire c. This mirror D is inclined upward and rearward, asshown, at such an angle that by looking at the mirror through slot a theeggs contained in opening C are clearly seen retlected therein. Themirror D is mounted on a suitable support, d, as shown.

In order to concentrate the light on the eggs being tested, I use amovable or adj ustable reflector, E, as shown. This reliector consistsof a wide board, preferably made ofa white wood or else painted white;or, if desired,the surface of reflector E may be covered with brightmetal or mirror-glass. The use of glass, however, isnot very desirable,as it is apt to be soon broken.

The reflector E corresponds in length to box A, and is secured thereonon the side of slot a by means of metallic straps F F, secured to theends of the reiiector and extended, as shown, and pivoted on the endsofthe box by screws f or other proper means. The straps Fare bent, asshown, so that when down the reflector E lies just below the slot a andinclines outwardly and downwardly therefrom, and when raised thereflector E stands above slot a and inclines slightly inward over theeggs placed in openings C, soasto concentrate the light thereon, andtransmit it by reflection through the eggs vupon mirror D.

If desired, the outer edge, e, of reflector E may be inclined inward tomore powerfully concentrate the light. top B are cut away, as shown at bb, to accommodate the straps F when the reiiector is raised. Y

The described parts are all that have tobe employed when testing eggs bydaylight, and the manner of using the same is as follows: The reliectorE being lowered,eggs corresponding to the number of openings C areplaced in said openings. The reflector E is then raised, concentratingthe light on the eggs, as described. Then by looking through slot a theuser can readily tell from the reliection of the eggs in the mirrorwhether they are fresh or stale, as will be readily understood. Thereiiector is lowered to remove the eggs after they have been tested. Insome instances I employ a slide, e', for regulating the width of slot a,so as to exclude as much light as convenient from the interior of box A,by which the condition of the eggs can be more clearly seen in themirror D.

In order to adapt the tester for use at night,

The projecting ends of 8o I employ the removable top G, as shown, aboutcorresponding in size and form to box A, but having no bottom, and itsfront face is inclined at au angle corresponding to the inclination ofreflector E When raised, and has an opening at its lower portioncorresponding in size to the reliector E, so that when properly adjustedon top of box A its front side will be closed by said rellector whenraised. This top G is removably secured on box A by means of lingers gg,secured to the lower edges of the ends ol' top G, which embrace theprojecting edges of top B, as shown. The interiors of box A and top Gare preferably painted a light color.

H designates a lamp placed on and centrally of the lengt-h of top B tothe side of openings C. The ilue or chimney of this lamp passes througha corresponding opening, z, iu the top G, as shown. The top G beingpreferably adjusted on box A and lamp II lighted, the eggs are placed inopenings C C, as before, and the reflector E raised, concentrating thelight on and reflecting it through the eggs, as before, so that theirquality is readily detected by a person looking through slot a. ITherelector E, constructed and operating as described, it will be observed,serves a very useful p u rposc and greatly increases the efficiency ofthe tester, and I consider it one of the essential elements of myinvention.

Having described my invention, what I claim 1sl. The combination of thebox A, having egg-openings C in its top, the supporting-Wire c, belowsaid openings, and the sight-slot a in its side below the egg-opening,and provided with an adjusting slide, e', with the inclined mirror D,secured in the box A, below and to one side of the openings G and facingslot a, and the movable reflector E, secured to box A by benthinge-straps F F, all constructed and arranged substantially as and forthe purpose described.

2. The combination, with the box A, provided with egg openings C in itstop and sight-slot a in its side, and the mirror l), se cured within boxA, and the exterior adjustable reiiector, E, constructed substantiallyas described, movably secured to box A by bent straps F F, of the top G,removably secured on top of box A, having a front opening adapted to beclosed by rellector E when lthe latter is raised. and a lampilucopening, h, and the lamp H, all constructed and arranged substantiallyas and in the manner and for thc purpose described.

In testimony thatI claim theforegoing as my own I affix my signature inpresence oftwo witnesses.
